  1. I have the DM-N910P Note 4. It is rooted and I have TWRP recovery. I wonder if the problem could be that when I try to download from “here”, it takes me to a broken page. The only way I could get a download was tapping “mirror?” I checked, and it was a zip file.

  2. Yes, I have the SM-N910P with Lollipop 5.0.1. I am rooted with TWRP recovery.
    I am going to try downloading it again, and this time check the folder the zip file is in – make sure it downloaded completely.

  3. Yeah, I tried it, and kept getting force closures. Tried both of your fixes – no good. Deleted.
